A method is presented to measure the radio-frequency (RF) vector magnetic field inside an object using resonance imaging (MRI). Conventional " [Formula: see text] mapping" in MRI can proton co-rotating component ( of RF produced by a transmit coil. Here we show that repeating mapping on same and coil at multiple (8) specific orientations with respect main magnet, magnitudes relative phases all (x, y, z) Cartesian components be determined unambiguously. We demonstrate circularly polarized...
Magnetic resonance imaging (MRI) using an ultra-high magnetic field (7 Tesla) enables detailed and non-invasive studies of the function anatomy human visual cortex, which is brain region responsible for signal processing. However, 7T MRI often suffers from image shading in occipital due to radiofrequency (RF) wave propagation effect. Dedicated cortex coils, on other hand, lack capability visualize whole necessary registration. We propose a novel RF coil structure 2-channel transmit receive...
In this study, we propose a novel, multiturn histology coil for microscopic magnetic resonance (MR) imaging of histological tissue slices with substantially higher signal-to-noise-ratio (SNR) outcomes compared previously developed coils. We performed electromagnetic simulations the proposed coils and acquired MR images from gelatin phantom rat brain slice implemented The performances were evaluated by comparing measured simulated radio-frequency transmission (B<sub>1</sub><sup>+</sup>)...
